REPRODUCTIONReproduction is the biological process by which new
"offspring" are produced from their "parents”
Two main types: sexual and asexual
Sexual reproduction typically requires the involvement of two gametes, one each from opposite type of sex

FERTILISATION
Fertilisation is the fusion of gametes to
produce a new organism.

Hormone of female reproductionFollicle stimulating
hormone - FSHLuteinizing hormone – LHIn accordance with ovary
cycle, menstrual cycleImportant in assisted
reproductive technology

One and only one sperm can penetrate and fertilize with the oocyte
